A simplified preparation of erythrocytes (rbc) for rbc pyrimidine 5′-nucleotidase (P5N) is described and correlated with blood lead. Washed but unfiltered rbc are incubated with uridine monophosphate (UMP) and the amount of uridine liberated is measured by high performance liquid chromatography (HPLC). UMPase activity of unfiltered rbc of 20 normal subjects was 12.4 ± 2.4 units, comparable to reported data obtained under varying conditions of preparation and P5N assay. In 20 lead-exposed adults and 20 controls, the regression coefficient for blood lead (PbB) predicted by rbc UMPase was in PbB = 4.77 − 0.22 UMPase; r2= .61. If UMPase ≤ 7.6 units (mean, 2.0 SD) is considered abnormal, sensitivity for prediction of a blood lead ≥ 40 Ég/dL is 80%. Specificity, the percent of subjects with a UMPase > 7.6 units who had a blood lead < 40 µg/dL, was 96%. Wider utilization of P5N, measured as UMPase, is proposed as a biologic correlate of blood lead.
